2 Claims.

My invention relates to improvements in rubber or hand stamps of the type commonly used in banks and ofiices.

It is well known that in the use of stamps of this kind the users hand grasping the handle is brought forcibly into contact with the wooden block in which the type is set each time the stamp is brought downward on the paper or other article stamped and this results, where the stamp is used to any considerable amount, first in forming a sore or bruised spot usually at the junction of the little finger with the hand and finally in the formation of a callosity at this point.

With the above in view it is the main object of my invention to provide a cushion to relieve the hand of the sharp contact with the wooden stamp block, this cushion being preferably in the form of a sponge rubber pad secured on the upper surface of the block but of course acting with equal efiiciency if made of another resilient material such as felt or other fabric.

The foregoing and other objects together with means whereby the same may be carried into effect will best be understood from the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a side view of a stamp in which is embodied my invention.

Figure 2 is a view similar to Figure l but showing the block and cushion in cross section.

Figure 3 is a plan view of the cushion alone.

Referring now with greater particularity to the drawing the numeral 5 designates the wooden block of a conventional form of stamp 6 on the lower face of which the usual rubber type '7 is secured. A handle 8 is secured medially and in a vertically upstanding position on the upper face of the block 5 by a wood screw 9 which is extended from its lower end and screwed into the block. a

In the use of a stamp so constructed the hand of the user is brought repeatedly into sharp contact with the upper face 5a of the block 5 and becomes calloused on the side striking the block. To avoid this and in acordance with my invention I provide a pad or cushion 10 formed of soft sponge rubber or other resilient and yielding material and of such size and shape as to completely cover the upper face of the block 5 on which it is mounted and held in any suitable manner. Medially the pad 10 has an aperture 11 to pass the ferrule end 12 of the handle 8 and as one means of securing the pad to the block this end of the handle may have an overhanging marginal shoulder 12a to overlie the margin of the aperture 11 and bear on the pad when the handle is screwed home. The pad might also be glued to the block if desired.

So arranged the pad 10 absorbs and cushions the shock of the hand as the stamp is used and completely overcomes the objectional and injurious effect on the hand. Further details of arrangement and utility will be apparent without further description at this point.

While I have herein set forth a certain preferred embodiment of my invention it is understood that I may vary from the same in minor structural details so as best to provide a practical device for the purposes intended, not departing from the spirit of the invention and within the scope of the appended claims.

I claim:

1. In combination with a stamp including a block and a handle secured to the upper face of the block, a pad of resilient yielding material secured to the upper face of the block and completely covering the same, the said pad having an aperture to pass the said handle.

2. In combination with a hand stamp including a block and a rigid handle rigidly secured to the upper face thereof, a pad of resilient material substantially covering the upper face of the block, the said pad having an aperture to pass the said handle.
